Add Cron in 'Pi-hole as All-Around DNS Solution' guide

Wouldn't it be good to include the following in the cron for let's say the weekly update query?

Important: Download the current root hints file (the list of primary root servers which are serving the domain "." - the root domain). Update it roughly every six months. Note that this file changes infrequently.

Copied to clipboard
wget -O root.hints https://www.internic.net/domain/named.root
sudo mv root.hints /var/lib/unbound/

That is an optional step for unbound (the update step).

Pi-hole does not come bundled with unbound and thus, the need for it is not justified, until the user choses to use unblund also, which again is optional.
If one goes through the steps of installing and configuring unbound, editing the crontab for one line should not be an issue ...

An additional option, one that I use. I made a 6 month calendar reminder to check the root.hints file on the web for changes, and update manually if necessary.
